Manson Construction Co. v. County of Contra CostaAnnotate this Case
Manson owns heavy marine construction and dredging equipment, including 60 specialized vessels and over 50 barges. After the Contra Costa County Assessor’s Office assessed property taxes on the value of Manson’s vessels for tax years 2013 and 2014, Manson filed administrative appeals, claiming some of its vessels were exempt from taxation under the Vessel Use Exemption, which provides that “[v]essels of more than 50 tons burden in this State and engaged in the transportation of freight or passengers” “are exempt from property taxation,” Cal. Const. art. XIII, section 3(l). The Board denied Manson’s appeals.
The trial court and court of appeal affirmed. Manson did not establish that anyone owned or controlled the sludge it dredged, or that the dredged material could be considered goods, delivered from a consignor to a consignee. The dump scows and barges were moved from the harbor to disposal sites for the purpose of being emptied out so that they could return to the harbor and continue to perform the work for which they were hired; the carrying of the dredged material from the harbor to the disposal sites was merely a necessary byproduct of, and incidental to, that dredging work. Manson’s vessels were engaged in dredging, not in the transportation of goods for hire.
